TO aZZ whom, 't may concerm Be it known that we, WILLIAM GATES andADOLPHUS G. SNELL, of New Haven, in the county of New Haven and State ofConnecti cut, haveinventcd a new Improvement in Carriage Canopy-Joints;and we do hereby declare the following, when taken in connection withaccompanying drawings and the letters of reference marked thereon, to bea full, clear, and exact description of the same, and which saiddrawings eonstitute part of this specification, and represent, in

Figur-e 1, a side View of a portion of the canopy-snpporting rod and thecanopy-joint; Fig. 2, an end view of the same; Fig. 3, a longitndinalcentral section through the sleeve D, producing a transverse sectionthrough the sleeve G; Fig. 4, a transverse section through the sleeve D,produeing a longitudinal section through the sleeve G; Figs. 5 and G,modifications.

his invcntion rclates to an improvement in canopies for children scarriages, and particularly to the joint by which the canopy is securedto the supporting-red, the object oi' the invention being to construct africtioujoint whe'eby the canopy may be universally adiusted and held atany point to which it may be adjusted without other securing devicesthan that afforded by the friction of thejoint itself; and it consistsin the construction as hereinafter described, and particularly recitedin the claims.

A represents the npper end portion of the rod by which the canopy isattached to the carriage-body. The Construction of the rod and itsattachment to the body may be any of the known contrvanoes for thispurpose. The rod terminates in a pivot, B, which projects from ashoulder, C, on the rod. This pivot B is cylindrical in shape, exceptthat it is flattened upon one side, as at a, (see Fig. 4,) and usuallythe axis of the pivot is horizontal. Onto the pivot B a sleeve, D, isplaced, the interier of the sleeve being of a shape corresponding to thepivot, except as to the fiat portion, and so that the sleeve may turnfreely upon the pivot as its axis. To produce a frietion between thepivot and its sleeve,a featherspring, E, is introduced between the fiatside of the spindle and the inner .surface of the made as a part of thesleeve D.

sleeve. This spring is somewhat thinner than the depth of the said spaceand is eurved, and so that as it is forced into the space between thesleeve and flat side of the spindle the spring will be compressed, andso that its re active force will be applied between the pintle andsleeve to produce strong frictional contact between the spindle andsleeve, but yet so that the sleeve may be turned upon its pivot to theright or left by applying suificient force thereto to overcome the saidf-iction. The sleeve is held upon the pivot by means ofa screw, F,introduced into the end of the spi-ndle, its head extending over the endof the sleeve, as seen in Fig. 3; or any of the known equivalents may besubstituted therefor.

Upon the sleeve D is a transverse sleeve, G, This sleeve G has anopening through it substantially the same as the opening through thesleeve D, except that the opening of the one sleeve is at right anglesto the opening through the other sleeve. This second sleeve carries thevertical canopy-soeket H. The socket itself is adapted to receive andhold the staff of the eanopy, and is constructed with a shank, I, whichterminates in a horizontal pivot, J- that is, at right angles to thesoeket. The pivot J corresponds to the opening through the sleeve G,except that upon one side it is llattencd, as at b, the same as thepivot B, and into the sleeve a spring, K, is introduced to bear upon theflat side of the pivot J,the same as does the spring E on the pivot B,and the pivot is Secured in the socket by a screw, L, like the screw Fin the pivot B, or an equivalent therefor.

The springs in each sleeve produce the frietion upon their respectivepivots suffcient to support the sleeve D on the standard and the socketin its sleeve, but yet so as to allow the sleeve D to be rotated uponits pivot or the soeket H to he rotatecl in its sleeve, so that the saidparts will stand at any point to which they may be adjnsted, and as theaxis ol' the pivot J is at right angles to the axis B it follows that auniversal adjustment of the socket H and the canopy it carries may beproduced, and because of such frictional appliance anymeehanically-operated device to secure the parts is avoided. TheConstruction is simple 'lOO and cheap, and because of the avoidance ofsuch mechanieal appliances it is only necessary to tilt the canopy tothe required positon, where it will rest firmly supported.

While we prefer to make the recess in the sleeve by simply fiatteningone side of the pivots,t11e longitudinal recess may be made by a groovein the pivot, as represented in Fig. 5, the spring being introduced inthat recess; or the longitudinal recess may be formed in the sleeve, asseen in Fig. 6, and the spring introduced therein, it only beingessential to the invention that there shall be a recess between thespring and sleeve, with a spring therein to produce strong frictionalbearing between the pivot and sleeve. Te, however, prefer to make thelongitudinal recess directly in the pivot.

It will be nnderstood that the socket H is to be constrncted accordingto the staff or de vice provided on the canopy 'for its attachment.

'We claim-- 1. The combination of the canopy-rod A, const'ncted with apivot, B, upon its upper end, the said pivot of eylindrical shape, eX-cept a longitudinal recess on one side, a sleeve, D, on said pivot, saidsleeve D constructed with a transverse sleeve,G, the eanopy-socket H,constructed with a pivot, J ,corresponding to the said sleeve G, exceptthat said pivot is recessed upon one side, with a spring within eachsleeve and in the recess in the pivots, substantially as and for thepurpose described.

2. The comhination of the canopy-rod con-- structed with a horizontalpivot at its upper end, a sleeve, D, on said pivot, the said sleeve Dconstructed with a transverse sleeve, G, can`opy-socket H, construetedwith a pivot, J, corresponding to the said sleeveG, with aspringarranged in each of said sleeves and in recesses between the saidsleevcs and their re WVILLIAM GATES.
